Allen Bradley 1775-P2 Power Supply Module
The Allen Bradley 1775-P2 is a multi-output power supply module engineered specifically for Allen-Bradley PLC-3 large-scale automation architectures. This heavy-duty hardware unit occupies a single slot within the chassis, converting standard single-phase AC line voltage into regulated DC rails required by rack-mounted processors and I/O modules. It provides maintenance personnel and control system integrators with a reliable power distribution backbone capable of delivering up to 28 amperes of total output current.
Input Power and Operational Flexibility
The power supply accepts a selectable or wide-range single-phase input voltage of 115 to 230 VAC operating across an input frequency range of 47 to 63 Hz. Internal input protection is managed via a dedicated built-in fuse to safeguard internal circuitry against line surges and electrical faults. Furthermore, the unit incorporates line-to-DC galvanic isolation to enhance operator safety and reduce electrical noise transmission from the AC mains into sensitive processor backplanes.
DC Outputs and System Protection
The module provides three distinct regulated DC outputs distributed directly through the PLC-3 backplane interface. To prevent catastrophic hardware failures under load anomalies, each output is fully protected against overcurrent and short-circuit conditions. Weighing 21.75 lbs (9.87 kg), the unit requires adequate ventilation and proper clearance within the control cabinet to dissipate heat generated during high-capacity operation.
